Lawyer-activist Prashant Bhushan today told the Supreme Court that he cannot reveal the name of the person who gave him access to details of a list of visitors to CBI chief Ranjit Sinha’s home, alleging that he fears for the person’s life.

The court had asked the senior lawyer to reveal the “name of the whistle-blower who had access to details of cars and people at the CBI chief’s house,” which Mr Bhushan had submitted in court earlier this month.

Mr Bhushan’s Centre for Public litigation or CPIL said in a statement that the information was received “from a confidential and reliable source whose identity needs to be protected.”

Mr Bhushan, who is a member of the Aam Aadmi Party, has accused Mr Sinha of compromising investigations into some of the country’s biggest financial scams by meeting the accused at home.

Mr Sinha has filed affidavits refuting the allegations. He has argued that Mr Bhushan is legally bound to reveal the source of the diary.

Speaking to NDTV, the CBI chief had explained why he met some of the accused at his Delhi home. “I have a residential office and there are many persons who would not like to meet me at the CBI Headquarters due to the undue publicity. Nobody can say I have shown any favours to persons I have allegedly met,” he said.
